it seems that even stock 350z guys get that rattle and most of their flywheels are destroyed, maybe a new flywheel or resurfacing might help, who knows, hope you guys figure it out, i'll probably be swapping this tranny into my 400 next summer

Halon would you estimate as loud as mine you think? i freaking hate that rattle.. i would pay good money to make it go away lol...
i hope it is not thrashing my engine bearings at least, when i clutch it just purrs
oldmantan the flywheel is new and has been doing it since new, i even pulled the trans to go over everything and there were no loose bolts or anything. maybe ill pull it out over christmas this year and take another look but hard to justify spending time if theres no fix.

Halon or anyone out there with the Collins adaptor plate/flywheel combo.How did you get the flywheel over the pilot bushing adaptor? I'm chewing it up badly and it's just not going in all the way to sit flush at all.

These trannys, when used with any aftermarket flywheel (and often even with stock flywheel) are inherently noisy.
The V160/161 has the same issue when removing the dual mass flywheel and using a normal one. They sound like a bunch of bolts or bearings rattling around. It is VERY exaggerated when using a lightweight flywheel/clutch setup like a twin plate or other.
Japanese clutch manufacturers call it "gear crashing" which is basically just the gear slop rattling when there is no load applied to the trans. There is actually a disclaimer on the instructions when you buy an EXEDY twin or equivalent. They tell you it is normal. And I've never had a problem with my V160/HKS twin both abusing it drifting or daily driving in the drift car.

Chiming in to agree with SERIALN9NE.
Automakers increased the gear lash inside the gearboxes to allow them to spin more freely. This increases overall efficiency, improving performance and fuel consumption.
To reduce the vibration and noise the increased lash causes, they use dual mass flywheels.
So anytime you're using a transmission that was intended to be used with a dual mass flywheel with a single mass flywheel, regardless of how many plates the clutch has, or how much dampening it provides, etc.. you're going to get that gear chatter.
BMW e46 guys fight this same battle. If you replace a dual mass flywheel that has worn out springs with a single mass flywheel (no springs to fail), you will get gear chatter. You're trading one ill for another.
A guy here at work with a ford diesel truck with a manual tranny has the same issue after switching to a single mass.
And most people agree... the gear chatter doesn't cause any issues, it's just annoying for a street car. When I did the clutch in my e46, I spent the money and installed a new OEM dual mass flywheel because it's a daily driver.

wow just looked up 350z and this rattle issue and there are tons of people talking about it even on cars that were relatively new and stock which would have the dual mass flywheel. wonder if it is bearable with that its kind of disappointing after all the custom work the trans rattles at idle.

It's really not that bad in my opinion. Noticeable sure, but not that bad. I have a really quiet exhaust setup so I hear it, but it's not bad. I've never had a single person even notice or ask about it yet. It's just being our cars, I think we notice when we hear something we aren't used to
